COLORED COMPOSITION SHEET.

Application filed June 22, 1915. Serial No. 35,583.

To all whom it may concern:

Be it known that I, RAY P. PERRY, a cit1- zen of the United States, residing in Montclair, New Jersey, have invented certain new and useful Improvements in Colored Composition Sheets, of which the following is a specification. g r

This invention provides for the making of colored sheets of material to be used for roofing, flooring and similar purposes. The improvement is preferablyapplied to bituminous fibrous composition sheets such as are described in the patent to James (J. Woodley,

No. 1,166,166, granted December 28, 1915, and

. 10,392, filed February 25, 1915, now Patent No. 1,201,? 56, or may be applied to the products commercially known as rubber roofing or composition roofing, with or without embedded reinforcements and in the specification and claims, the expression bituminous 'compositlon 1s 1ntended to include compositions with or without .fibers containedtherein.

The invention aims to produce all of such sheets in various colors by a method which shall be economical and which shall'at the same time provide a colored surface which is tough and has a good resistance to the elements when used for roofing and to wear when used for flooring. As an example,

reference is made .to the Woodley fibrous bituminous composition, above cited. This product cannot be satisfactorily produoedin light shades by merely incorporating therewith various coloring materials. For example, if it is desired to produce a llght brown or copper shade and it s attempted to incorporate in the composition suflicient pigment, such as ocher, iron 'oxid, etc., to produce the necessary color, t 1s found that the strength of the binder is deleteriously affected by the pigment and so much of the Specification of Letters Patent.

pigment is required in order to lighten the natural dark color of the binder, such as asphalt or pitch, that the resulting sheet is extremely weak and perishable and loses many desirable properties possessed by the original uncolored composition. Also if it were possible to get a product of suitable strength by such method, it would be relatively expensive on account of the high percentage of pigment required.

My experiments have led to the discovery that this coloring of the aforesaid .fibrous sheets can be satisfactorily accomplished without sacrificing any of the desirable qualities of said material and with a production of a substantially durable colored produce at much lower cost as follows:

A fibrous composition is prepared by first introducing twenty parts by weight of fibrous material, such as waste paper, to eighty parts of binder, such as asphalt or pitch, of the desired consistency, and then disintegrating the fibrous material without destroying the fibrous condition so that the fibers are distributed substantially homogeneously throughout the binder and are coated and cemented together, and in some cases in part saturated by the binder, yielding a tough, fibrous composition. A portion of this composition is formed between rolls or in any other desired way into a sheet of the desired width and thickness.

A suitable pigment is mixed with another portion of the fibrous-composition (or of the other known roofing compositions) in such proportions as to give the deslred shade or color and the resulting mixture is rolled or otherwise formed into a sheet. This colored sheet may be of any desired thickness Suficient to wear for the required length of time under the conditions for which it is intended to be used.

. A sheet of the uncolored composition is then united with a sheet of the colored composition by pressing the two together. Or if ,desired a sheet of the colored composition may be applied .to each of the surfaces of the uncolored sheet by pressing the three Preferably the sheets are united shortly afterbeing rolled into sheets while their surfaces are fresh so that they have a good cementing action. -The adherance of one sheet to the other is due to their natural colder they require a greater pressure, or if warmervthey may be united by a lower pres-.

sure. If desired, the two sheets may be cemented together by a binding'course of melted asphalt or pitch, etc., but under proper temperature conditions and with suitable pressure, the sheets themselves can ordlnarily be united satisfactorily. It will be noted that the product may have one or' both faces colored and yet, owing to the use of the uncolored base, we retain very considerable'strength, which is desirable in a product of this kind.

If desired, a sheet of one color may be applied on one face of the foundation sheet and a sheet of another color on the other face of the foundation sheet. Also the colored sheet need notbe of a single color but may be made of a mottled appearance by partly mixing together some uncolored composition with some colored composition and rolllng the mass in a state of incomplete mixture to I "form a sheet; or by applying the colored composition to portions only of the face of the uncolored composition, either irregularly or in a determinedpattern and rolling the mass down to a smooth face. Also similar results may be obtained by combining masses of two or more difierently colored compositions in the same way. And the invention includes articles which are either entirely or only partially faced with the artificially colored composition.

Also a sheet of colored fibrous composition may be cemented to any suitable base other than one of uncolored fibrous composition. For example, I may cement by heat or pressure, or in any other desired way, a sheet of colored fibrous composition on a foundation sheet or any roofing, felt or paper, or on a plain or saturated sheet: of

, cloth, or on a sheet of metal or of wood, or

on any other foundation which has the requisite strength and other characteristics required. The main idea in these cases is to use the artificially colored fibrous composition on a foundation having the required greater strength and other properties for the purpose in hand. This fibrous composition has naturally greater strength than non-fibrous bituminous compositions so that, even though weakened by the artificial color.- ing it is stronger than such non-fibrous bituminous composition would be when similarly colored. Nevertheless, the invention may be applied with advantage to other composition roofing, as above stated; or one sheet may be of the bituminous composition and another of any of the known roofing compositions above referred to.

The colored sheets are adapted to use for roofing, flooring, or siding purposes and may be put in rolls or the sheets may be cut toany desired size or cut to form shingles,

:- tiles, etc., or other forms as desired.

The accompanying drawings illustrate diagrammatically embodiments of the invention.

The composition is formed into sheets and these sheets then pressed together to make a composite sheet. The two steps of forming the sheets and uniting them may be carried out in asingle'operation or in separate operations. The drawings illustrate both methods.

Referring first to Fig. 1, there are co1n pression rolls'A revolving in the direction indicated by the arrows and separate rolls B which compress and spread the material against the upper portions of the rolls A in order to form the separate sheets. A supply of uncolored -fibrous composition is maintained at C and a similar supply of the artificially colored composition at I). These bodies of the composition are in plastic condition and are rolled out by the rolls A and B to form them into sheets, which sheets are carried down by the same rolling operation. to the space between the compression rolls A While they are still fresh and tacky and are there united by pressure to form the finished sheet E comprising the colored layer or sheet F constituting one face and the uncolored layer or sheet G constituting the other face. The invididual sheet-forming rolls B may be shifted toward and from the corresponding rolls A so as to regulate the relative quantities of the compositions C and D and their relative thicknesses inthe sheet; and the distance between the rolls A may be adjusted to vary the total thickness of the sheet.

sion rolls A, the formed sheets C and D being then fed upon the rolls Aat a point meant somewhat in} the rear of the compression point, whence they are brought together and united as previously explained by the rotation of the rolls A.

Or, as in Fig; 3, a spacing block B may be arranged between and above the compression rolls A' with its lower end tapered; the supply of the unformed compositions C and D being located between the respective rolls and the opposite sides of the tapered block so that they are compressed against the block into individual sheets and then carried down and united by the rotation of the rolls. The spacer B may be shifted laterally and vertically to regulate the relative quantities of the compositions (land D carried down between the rolls and the relative thicknesses of the layers F and G in the composite sheet.

For most uses the artificial color will be required on only one side. But the process may be extended to the applying of a coating ofIthe artificially colored composition F, F (Figs. 4 and 5) upon both sides of a layer or sheet G of uncolored composition; Or the process may. be applied to two compositions artificially but difierently colored so that the opposite faces of the sheet will be of difierent colors.

In Figs. 6 and 7 the uncolored sheet G has applied on one face of i-t a colored sheet F of a mottled appearance produced by incompletely mixing together colored or uncolored materials or'two materials which are differently colored artificially.

lFigs. 8 and 9 show a similar result obtained by applying on the uncolored base G separate portions F of artificially colored material and rolling them down to produce a smooth face on the finished product.

A similar process may be used to secure a composite sheet specially adapted for use in making composition shingles in accordance with the invention described in my a plication for Patent No. 16,8 19 filed March 25, 1915. According to the said invention a sheet is first formed which is of varying thickness, and is preferably uniformly tapered, in cross section, and this sheet is afterward cut to produce shingles thicker at one end than at the other. By the present invention a sheet may be made which is artificially colored al-onga portion of its face, which sheet may be. cut into shingles so that only the colored portions of the shingles will be exposed when they are laid with overlapping ends in the usual way. Such a sheet is indicated in Fig. 10 of greatest thickness in the center and tapering toward the opposite edges, the principal portion Gr of the composite sheet being of uncolored composition and an artificially colored band being formed by the layer'F of-artificially colored composition lying in its width across the thicker portion of the composite sheet.

over only a fraction of the width.

This sheet may then be cut along the central longitudinal line and divided by cross cuts' into shingles J, Fig. 11, the exposed portion of which is composed of the artificially colored layer F and the body and covered portion of which is composed of the uncolored layer G*. This shingle represents-a combination of the greatest strength with the greatest economy.-

Fig. 12 illustrates the manner of forming the tapered composite sheets. The comprespreviously formed into sheets C and D and carried on revoluble shafts H located alongside the compression rolls, and are fed while in plastic condition to the pass between the compression rolls. The sheet 0* 7 extends over nearly the entire width of the pass and the sheet l) is centrally located and extelrplds he sheets are made of such thickness that when compressed together they will make up the desired cross section and will be compressed into tapered shape and firmly united to each other as they are carried between the compression rolls.

Various other styles of blanks may be used in the manufacture of shingles. For ex ample, the body of the blank may be made into a sheet thinner at the center and thicker at the two edges, with a band of colored material at each edge. Or the sheet may be made wide enough to have several alternately thick and thin sections with colored strips along the thick sections. In these cases there would be not only one but several strips of the colored material.

Various other modifications of the product and process as described may be made by those skilled in the art without depart ing from the invention as'definedin the following claims.

What I claim is- 1. As a new article of manufacture the combination of a plurality of pre-fo-rmed sheets of bituminous composition united face to face, at least one of which is artificially colored.

2. As a new article of manufacture the combination of a plurality of pro-formed sheets of bituminous composition united face to face, one of said sheets being uncolored and another constituting the face of the article and being artificially colored.

8. As a new article of manufacture the- 10. As a new article of manufacturethe combination of a plurality of preformed sheets united face to face, one ofsaid sheets being made substantially of paper fibers and asphalt and another of said sheet-s being made of an artificially colored waterproofing composition.
